This chapter does not just deal with creating databases, tables, and querying them. It also deals with setting your database up in your Docker environment, which is a technical aspect of database knowledge that you should have.

Physical database design for relational databases
ACM Transactions on Database Systems, 1988This paper describes the concepts used in the implementation of DBDSGN, an experimental physical design tool for relational databases developed at the IBM San Jose Research Laboratory. Given a workload for System R (consisting of a set of SQL statements and their execution frequencies), DBDSGN suggests physical configurations for efficient performance.

Constraints, 1996
Recently, interest in constraints and databases has increased significantly as the databases field has started to consider broader application domains. In this short position statement, I identify some of the most promising direcrtions, in my opinion, for the use of constraints in the context of databaes management systems.

This chapter provides a history and overview of what is called “structured” journalism, journalism that grapples with a different conception of journalistic facts and the means by which these facts can be strung together to create news stories. Instead of using databases and social science methods to craft narratives, so-called computational or ...

Conceptual and Database Modelling of Graph Databases
Proceedings of the 20th International Database Engineering & Applications Symposium on - IDEAS '16, 2016Comparing graph databases with traditional, e.g., relational databases, some important database features are often missing there. Particularly, a graph database schema including integrity constraints is not explicitly defined, also a conceptual modelling is not used at all.

Temporality, or the time dimension is an essential aspect of the reality databases attempt to model and keep data about. However, in many database applications temporal data is treated in a rather ad hoc manner in spite of the fact that temporality should be an integral part of any data model.

Database Schemes and Databases
1991We attempt a more rigorous definition of the relational database model based on /THAL 88/ as it was originally introduced by E.F. Codd /CODD 70/ using the theory of abstract data types /REI 84/ and especially the approach of /PDGG 88/, /VOSS 87/ and /DEAB 85/.
